It's not horrible but it's not my favorite. The story is understandable, there aren't any bugs I encountered, and the controls aren't bad. The graphics weren't awful for an adventure game. It's clearly inspired by the scenes from Indiana Jones & The Last Crusade where he has to go through the three tests. The premise itself was pretty solid.
What I disliked about this game was the lack of variety in the puzzles. There are basically 3 or 4 main types of puzzles in this game (with maybe a couple others) and they all look exactly the same, they just get harder. I found them either frustratingly difficult or so easy it wasn't even a challenge. None of them felt "just right" where I got that "aha!" moment. It felt like it wasn't playtested, or if it was, maybe not enough.
The dialogue is mostly fine but some of it was awkward. The protagonist attempts to make jokes, but they really miss the mark and I didn't find them funny.
What took me so long to play this is that I couldn't figure out the first puzzle of the entire game so it just sat in my Library. For me that was the hardest one in the game. Once I looked up how to do it a year after I bought it, it was fine.
All in all I would say it might have potential in future episodes but this one as is I wouldn't recommend.
